Castelli #GIRO Siena Jersey - Men´s

Siena Jersey delivers Giro-inspired style with breathable comfort for everyday rides

What Our Gearhead® Experts Are Saying:

"The Siena Jersey is super comfortable and stylish—it nails that balance between performance and casual. The fabric breathes really well and the fit works for a variety of rides. It’s perfect for days when I want to ride hard but still feel relaxed."

A nod to Tuscany’s timeless beauty and the passion behind the Giro d’Italia, the Castelli Siena Jersey blends heritage aesthetics with performance-focused comfort. Designed with lightweight, breathable materials and a neutral fit, it’s the jersey we reach for on warm-weather rides that start slow and end with a little sprint.

The soft stretch fabric moves with us in and out of the saddle, while the raw-cut sleeves offer a clean feel and next-to-skin finish. Three rear pockets hold mid-ride essentials, and the full-length zipper gives us complete control over ventilation when the heat kicks up. Whether it’s a café cruise or a weekend climb, the Siena keeps us rolling in Giro-inspired comfort.
